In the 1950s, research on natural regionalization for highway was set out in China. This paper reviews its history and introduces the relative research in other countries. Based on the comparative analysis of the different research angles among different countries, suggestions about the future work are offered. The relations between physiographical indexes and the indexes directly related with highway engineering are suggested to be studied and the basic data for highway be tested and collected all over the country. These works will be of help to the guidance of regionalization for highway engineering. And the impact of highway on the geographical environment should also be considered in highway natural regionalization.
